Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • xDSL transmission method can, for example, the ADSL or HDSL Transmission methods are used. With such transmission methods depends on the maximum possible transmission capacity very dependent on the physical boundary conditions, those during the transmission process in the local loop network prevalence. For example, play length and diameter of the subscriber line and the guide in a bundle with other subscriber lines decisive role.
  • Service Node In typical subscriber line networks all connections from an assigned control logic, which is called Service Node (SN), controlled and supervised.
  • This service node leads, for example, for everyone request from the subscriber or from the network to establish a connection a 'Connection Admission Control'. This means, that a check is made to determine whether it is sufficient Transmission capacity is available to the connect the required connection to the subscriber.
  • the subscriber lines are over on both sides Modem units completed.
  • the modems currently available adapt themselves to the currently existing physical Boundary conditions. These conditions change for example, that another xDSL subscriber in the the same line bundle is added, so the modems adapt again, as the transmission capacity may be necessary for example reduced by crosstalk becomes. As a result, the available bandwidth is reduced becomes.
  • the invention has for its object to show a way such as the transmission of information in subscriber access networks be made more flexible for xDSL participants can.
  • the invention is based on the in the preamble of claim 1 specified by the characteristics in the license plate specified features solved.
  • a particular advantage of the invention is that there is no service interruption is made if after the adaptation process less bandwidth is available. If a higher bandwidth is available, this can be immediately from Users.
  • a subscriber line network AN which is brought up to a plurality of subscribers TLN 1 ... TLN n .
  • Modem units M 1 ... M n are arranged in the subscriber line network AN, via which information is transmitted to the respectively assigned subscribers TLN 1 ..TLN n .
  • the settings in the subscriber line network AN are recorded and managed by an assigned service node SN.
  • the invention it is proposed to create a special maintenance communication between an xDSL modem unit M x and the service node SN. If the physical boundary conditions change, for example because crosstalk occurs from one of the other participants in the bundle, the modems adapt again, since the transmission capacity may be reduced. In this case, this circumstance is now communicated to the service node SN via the maintenance communication. If the bandwidth is reduced, the new bandwidth can be examined to determine whether new connections can still be allowed.
  • the special maintenance communication is implemented by introducing a maintenance communication channel K between the xDSL modem unit M x and the service node SN. This allows the connection control mechanisms to remain in the servide node.
  • the basic architectures of existing and future subscriber line networks can also remain the same. This entails a considerable reduction in costs for the network operator. If there is a higher transmission capacity with a new adaptation of the xDSL line, this procedure allows this capacity to be used. This provides the subscriber with a better service and increases the network operator's revenue opportunities.
  • the coupling between the xDSL modem unit and the service Nodes can be done in any way. So the maintenance communication channel K between the service node SN and the network-side or the subscriber-side modem units be switched. This makes xDSL routes possible in operation even when the transmission capacity changes maintain and reduce service downtime.
  • the communication channel K can, for example, be its own Time slot in TDM systems as well as a separate ATM channel or special ATM control cells in ATM based networks will be realized. In the same way is a realization or also possible via radio link. Furthermore it is conceivable, this communication channel via a TMN connection to realize.
  • the exchange of information can be periodic or if necessary.
  • the xDSL modem unit independently with the service node to let communicate or only on queries. Should there are several xDSL modem units in the local loop network their communication channels bundle to a service node. There are also certain Minimum transfer rates and / or the change granularity pretend.
  • the information of the actually available xDSL transmission capacity of course also for purposes other than that 'connection admission control' can be used.
